Mineralogical - geochemical characteristics of gold mineralization and its potential in the Tuong Duong area, Nghe An province

Abstract

Tuong Duong area, Nghe An province is considered as a high potential area of gold deposits such as the Yen Na - Yen Tinh, Ban Bon, Xieng Lip, and Na Khom gold occurrences. Based on synthesizing, geological processing data, analysis and complement of the 15 thin sections, 10 thick sections, 02 scanning electron microscope and 05 ICP - MS samples, results show that the gold mineralization has fomed from hydrothermal activities at low - moderate temperature, belonging to quartz - sulfur - gold mineral deposit type. The gold contents in orebodies vary from medium to high values, with average contents ranging from 0.8÷6.55 (g/ton). Results also provide an overview of the prospect of gold resources, serving as a basis for determining the Au prospective areas in Tuong Duong, Nghe An province. The direct calculation method for metallization parameters and Huvo methods are applied in this paper to estimate gold resources in the study area, resulting in 2.21 tons of Au - metal.

Mineralogical and geological characteristics and potential of iron resources in Tan An area, Yen Bai province

“…Mineral resource estimation holds significant practical importance in mineral investigation, as emphasized by previous studies (Zhang & Huang, 2010;Kuzvart & Böhmer, 1986;Hung et al, 2020;Hung and Dung, 2021;Hung and Cong, 2021;Hung and Tri, 2021;Khang and Hung, 2022). It provides a scientific and practical foundation for organizing geological survey programs and assessing mineral and investment opportunities.…”

“…Recently, numerous geological and statistical approaches have been developed for estimating mineral resources. Among these, similarityanalogy in ore geology and mineral resource estimation based on Huvo methods have been widely adopted to investigate mineral resources (Byryukov, 1962;Zhang & Huang, 2010;Hung et al, 2020;Hung and Dung, 2021;Hung and Cong, 2021). Various estimation methods have been employed for different scenarios depending on factors such as ore boundaries, geological geometry, grade variability, and available time and resources.…”
